What to expect

  • After arriving 15 minutes prior to your scheduled party time, you’ll find signage in front of the Center that states "The Party Starts Here!". Neither you nor any of your guests will need to get in line.
  • You will be greeted by your party host who will assist with check-in. You will provide your guest list to your party host, receive wristbands for you and your guests that will be present in our private party room, purchase additional adult tickets for your guests, and be led to the private party room at the start of your event.
  • When arriving at your private party room, you’ll find:
    • The room decorated with wall theming (letters spelling happy birthday and LEGO characters) and non-allergenic permanently installed balloons.
    • Colorful bins with LEGO brick will be placed on the tables for the build activities.
  • The age appropriate build activity will be conducted by your party host first and will last 15-30 minutes (depending on which package you have selected).
  • At the end of the build activity, beverages and pizza (if you’ve purchased the Premium or Ultimate Package) will be served.
  • The last thing served is the colorful, multi-colored icing cupcakes. The party host will bring the cupcakes into the room with candles to light so the party can sing happy birthday to the birthday child and have an exclusive LEGOLAND Discovery Center birthday video to follow. The cupcakes are very easy to serve, so when the video is over guests can help themselves and the party host will assist.
  • [Ultimate Party only] The meet-and-greet with Bertie, our LEGOLAND Discovery Center mascot, or one of his LEGO friends will take place. This is the perfect opportunity to take pictures with your favorite LEGO minifigure while in the party room.
  • Once the time in the party room is up, our party host(s) can assist in bringing any gifts or additional items to your vehicle. Any leftover food will be stored in our café & coffee shop and can be claimed when you conclude your stay. We will not be able to store personal belongings in the party rooms as we will need to prepare them for the following scheduled parties.
  • You and your guests are then free to enjoy the Center and its attractions for the remainder of your party after the time in the private room is up. Typically, guests spend 2 hours in the Center following the party room festivities. Your party host does not remain with you during this time and any additional beverages or food needed while in the Center are not complimentary.
  • If you wish, guest pick-up can take place in front of the Center where check-in/drop-off took place. Birthday parents generally communicate this to any parents who are just dropping off/picking up their children for the party.
